What is a green roof growing medium system?

A green roof growing medium system is a type of roofing system that uses plants and growing media (such as soil or compost) to help absorb rainwater and filter pollutants from the air. These systems typically include layers that help protect the roofing membrane, drainage layers, and various types of growing media and plant materials. Green roof growing medium systems are often used as an eco-friendly alternative to traditional roofing systems, as they can help reduce urban heat island effects, improve air quality, and provide natural insulation for buildings.
